Title: Optical fiber applied sensor device
Inventor: TODA KAZUO
IPC: G01R15/24
Filed: 1985-02-14
Abstract: PURPOSE:To measure plural different object physical quantities at the same time by separating variations in physical quantity of objects of measurement through filters at plural sensor parts and calculating a modulation degree. CONSTITUTION:Projection light from a light source 20 is transmitted to a temperature sensor 22 through an optical fiber 21 and its output light is modulated by a current sensor 24 according to the level of a current. Then, the modulated light is converted by an optical receiving part 26 into an electric signal, which is passed through LPFs 28 and 30, thereby outputting a voltage corresponding to the detected temperature of the sensor 22 to an output terminal 32. Outputs 29 and 31 of the LPFs 28 and 30, on the other hand, are inputted to a subtracter 33 to obtain a subtracter output 3. Then, the outputs 31 and 34 are inputted to a divider 35 to perform division using the output 31 as a denominator, so that a voltage corresponding to the current detected by the sensor 24 appears at an output terminal 36. Thus, different physical quantities of temperature and current are measured simultaneously through the constitution of the sample optical fiber transmission system and signal processing circuit.

IPC: B67D7/32
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a control valve which can simply check a valve opening retaining mechanism by opening a sensor tube communicating with a diaphragm chamber of the mechanism at a full-level tank position, and providing operation inspecting means for interrupting the communication with an opening on the way of the tube and then pressurizing in the chamber. CONSTITUTION:If oil is erroneously poured substantially in full state of a tank 68, oil level in the tank 68 is raised to reach full-level tank position L. Then, the air in a sensor tube 30 is urged by the oil to become positive pressure. This positive pressure acts a right chamber 22b to displace leftward a diaphragm 23 against a spring 26, and a clamping pin 25 is moved leftward, thereby releasing the clamp of a clamping groove 18b. If a main valve 17 is closed due to erroneous oil pouring, when a base valve of a lorry is closed, knob 20 is pulled up to open the valve 17 and then returned to its original state, the oil in an oil pouring tube 3 is fed down in the tank 68. If the operation of a valve opening retaining mechanism A is checked, when a cover 27 is pressed, a first spring 35 is contracted, a piston 33 is moved leftward to close a passage 31b, i.e., the tube 30.

Title: Gas laser apparatus
Inventor: ITOU NORIAKI
IPC: H01S3/038
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a discharge electrode whose corrosion-resistant property to halogens is high, whose cost is low and whose discharge-resistant property is high by a method wherein a discharge part of the discharge electrode for a gas laser apparatus is formed of an alloy which is composed mainly of tantalum and nickel. CONSTITUTION:The surface of respective discharge parts 11c, 12c is formed of an alloy which is composed mainly of tantalum and nickel. Since the melting point of tantalum out of them is high, it is hardly melted by an electric discharge. Since nickel is reacted with halogens such as fluorine and the like and forms a nickel halogenide as a passive state on the surface, it is possible to prevent the corrosion from progressing to the inside. Since the nickel halogenide has a low insulating property and is easily evaporated by the electric discharge, the surface of the discharge part is hard to insulate. As a result, it is not required to strictly control the composition ratio of the alloy.

Title: Removal of gallium
Inventor: KOSHIBA SHOHEI
IPC: H01L21/203
Filed: 1987-02-09
Abstract: PURPOSE:To enable removing gallium adhered to the stage of a manipulator without destroying the vacuum of a growing chamber by mounting an aluminum piece which is larger than the quantity of the gallium adhered on the stage, e.g., one which is the same shape to a wafer. CONSTITUTION:If gallium adheres to stages 4, 4', not only a wafer 2 is made dirty but also it is feared that the wafer 2 cannot be transferred due to the surface tension of the melted gallium. For this reason, the gallium is removed by using an aluminum piece. For example, an aluminum plate 5 has the same shape to the wafer and is mounted on the stages 4, 4' of a manipulator without destroying the vacuum of a growing chamber by using the transfer system of a molecular beam epitaxial equipment. If the stages 4, 4' are kept above the melting point of the gallium, the gallium adhered on the stages 4, 4' is absorbed in the aluminum plate 5 within approx. several hours. The aluminum plate 5 which finished absorbing the gallium is brought out of the growing chamber again without destroying the vacuum of the growing chamber by using the transfer system.

Filed: 1989-02-07
Abstract: PURPOSE:To cover discolored spots and to reduce deterioration caused by direct sun light by constituting the curtain of curtain texture, a shading layer containing photochromic ingredients formed on the curtain texture and a coating layer covering the shading layer. CONSTITUTION:On the curtain texture A formed of a resin film, a shading layer B containing photochromic components and a coating layer C are formed. Resin films like polyvinyl chloride are used as the curtain texture A. Next as the shading layer B either a resin film containing photochromic ingredients is bonded with adhesives or a resin solution like polyacrylic ester and SBR containing photochromic ingredients is coated. As photochromic ingredients those that deepen their colors when exposed to light and that take only a short time in the change of their colors in both reversible direction between the original and the changed colors are desirable, and dithizone quicksilver can be used. Favorably the coating layer C is formed by applying polyurethane or SBR resin solution, or foaming coating is applied by using foaming agent and foam stabilizer. But polyacrylic ester is more favorable.
